PATRICK M. WILLIAMS, OF NORTH WILKESBOBO, NORTH CAROLINA, ASSIGNOR TOMOORE DRY KILN COMPANY, OF JACKSONVILLE, FLORIDA, A CORPORATION OFFLORIDA.

VENEER KILN.

Application filed November 20, 1920. Serial No. 425,473.

To all whom it may concern:

Be it known that PATRICK M. vvinnnnus, a citizen of the United States,residing at North lVilkesboro, in the county of 'l Vilkes and State ofNorth Carolina has invented certain new and useful Improvements inVeneer Kilns, of which the following is a specification.

This invention relates to an improvement in veneer kilns and is of thegeneral type of the invention set forth in my application Serial No.383,530, and the fundamental object oi this invention is to provideadjustable dampers for regulating the hot air passage into the kiln.

In the accompanying drawings Figure 1 is a sectional view of a portionof a kiln.

Figure 2 is a view of a slightly modified construction. 1

Figure 3 is a perspective View of the intake end of the kiln.

Figure 4- is a view showing the suction fans at the end of the kiln.

It represents the kiln shown in Figure 1. There are a series of heatingcoils 1, preferably five in number, with headers 2 and 3, at oppositeends and extending transversely thereof. The air inlet 4, is controlledby hinged doors 5, and the hot air passage or throat 6, is regulated andcontroiled by two dampers 7 and 8 extending respectively from the roofand floor and one or both of which are connected thereto by hinges 9,whereby either one or both may be adjusted to regulate the size of thethroat 6, according to the amount of heat required in the kiln chamberand are adapted to direct the heat toward the bottom of the kiln.

In the modified tlorm. shown in Iiigure 2, the ventih-iting dampers areslightly ditferenl, the lower damper 11, being rigid and the upperdamper 12, being hinged and adjustableQ In the upper damper 12, slots13, are formed so that even when the adjustable dampers are closed thereis still a limited air passage through the throat.

In the construction shown in Figure 2 the headers 14 and 15, are bothlocated at the outer end and there are 6 coils of pipes. In bothiorins'it will he observed that the air is heated on entering the kilnit being circulated by suction or pressure fans 16. shown in Figure Boththe intake and outlet are controlled by adjustable doors or dampers sothat the degree of heat of the air may be re alater. to suit therequirements preparatory to passing through the kiln.

I claim-- 1. A horizontal kiln having a heated chamber and a dryingchamber, an upstanding damper and a swingingly adjustable dependentdamper overhanging the latter forming an adjustable throat between thetwo chambers.

A. horizontal kiln including a heated chamber and a drying chamber andtwo overlapping dampers one being swingingly ustabie and "forming anadjustable throat between the two chambers.

3. A horizontal kiln having a heating chamber and drying chamber, athroat be tween the chambers comprising an upstanddamper substantiallyperpendicular the iioor of the kiln, and a dependent damper of the kilnoverhanging said upstanding.

damper at an angle thereto there being an opening between said dampers.

i. A horizontal kiln having a heatingchamber and a drying cl'iamher, athroat between the chambers comprising an upstanding dampersubstantially perpendicular to the floor of the kiln, and a dependentdamper ot' the kiln overhanging said upstanding damper at an anglethereto there being an opening between said dampers, one of said dampersbeing swingingly adjustable relative to the other of said dampers.

In testimony whereof I afiix my signature.

PATRICK M. WVILLIAMS.
